प्रश्न
State two factors upon which the rate of emission of thermions depends.
उत्तर
Factors on which the rate of emission of thermions depends:
1) Nature of the metal surface: Lower the work function of the metal, greater is the rate of emission of electrons.
2) The temperature of the surface: Higher the temperature of the surface, greater is the rate of emission of electrons.

Derive an expression for the amount of heat given out or taken up, when its temperature falls or rises by t°C.
Calculate the total amount of heat required to convert 100g ice at 0°C to steam at 100°C.
(Specific latent heat of fusion of ice = 336 J/g, specific latent heat of vaporization of steam = 2260 J/g, specific heat capacity of water = 4.2 J/g°C).
Steam at 100°C is passed over 1000 g of ice at 0°C. After some time, 600 g of ice at 0°C is left and 450 g of water at 0°C is formed. Calculate the specific latent heat of vaporization of steam (Given: specific heat capacity of water = 4200 J/kg°C, specific latent heat of fusion of ice = 336,000 J/kg.)
